To provide a firmer base for the unit, you can choose to attach four
rubber feet to the switch chassis. Use the rubber feet and the four M4 x 8
Phillips screws included in the hardware kit.
To insert the power supply, switching modules, and interface cards,
configure optical ports for the interface modules and connect network
cabling and power to the unit see Chapter 4.
Distribution Rack
Installation
You can mount the CoreBuilder 7000 family ATM switch in a 19-inch
distribution rack. This section describes how to prepare the unit and the
distribution rack, and mount the unit in the distribution rack. Please read
all of the instructions carefully before beginning the installation.
For the basic mechanical and space requirements for the distribution rack,
see “Distribution Rack Requirements” on page 107.
Unit and Rack
Preparation
To prepare the CoreBuilder 7000 family ATM switch and distribution rack
for installation:
1 Attach the mounting brackets onto the sides of the CoreBuilder 7000
family ATM switch using the mounting bracket screws (M4 x 8 Phillips).
2
Determine whether or not the distribution rack has threaded holes. If the
holes are threaded, see “Mounting the CoreBuilder 7000 Family ATM
Switch” on page 28.
3
If the holes are not threaded, you must insert “G” clips. To determine
where to insert “G” clips, locate the top of a universal mounting hole
pattern on the left mounting rail. In the universal rail pattern, the spacing
between holes is 1/2 inch, 5/8 inch, 5/8 inch, and 1/2 inch. To find the top
of the pattern, locate the midpoint between any two holes that are
spaced half an inch apart. Figure 2 shows the universal mounting hole
pattern.
